Application May 21, 1937. Serial No. 144,028

In'ltaly May 23, 1936 p 1 cum. (c1. zusa) This invention relates toimprovements in propelling mechanisms and more particularly topropelling mechanism for air craft, water craft and the like. One objectis to provide means adapted to be built into air gliders whereby thistype of transportation may be adapted to travel with, or against, aircurrents; to rise and dip as may be desired and to steer readily.

A further object is to provide foot-operated power means for small watercraft whereby great speed may be attained with little effort, and in-With the foregoing and other objects in view the invention consists inthe combination and go arrangement of parts to be hereinafter fullydescribed, pointed out in the claim and illustrated in the accompanyingdrawings which form a part of this application for patent and in which-5 Fig. 1 is a view of the mechanism in side elevation.

Fig. 2 is a fragmentary plan view, enlarged, of Fig. 1. Fig. 3 is anenlarged cross sectional view through Fig. 2 on the line 3-3 thereof.Fig. 4 is a similar view on the line 4-4 of Fig. 2, but looking in theopposite direction.

Fig. 5 is an enlarged view, in elevation, of a locking pin employed.Fig. 6 is a plan view of the gearing employed and the supportingframework therefor. Fig. '7 is an enlarged vertical transverse sectionalview through Fig. 6 on the line thereof. 7 0 Fig. 8 is a similar view onthe line 8-4 of Fig. 6, looking in the opposite direction. Fig. 9 is atop plan view of Fig. 10. Fig. 10 is a view of Fig. 9 in elevation. Fig.11 is an enlarged fragmentary view, in 45 plan, of the double-tootheddriving gear and meshing pinions, with supporting frame. Like referencecharacters denote corresponding parts throughout the several views.

The present: invention includes a frame having 5 a steering post jacketi connected by the top bar 2 to the seat post 3 provided withthe seat 4.Journaled in a hearing at the lower end of the seat post is the pedalshaft 5 provided with the pedals 6 and fast to said pedal shaft is theas double-toothed drive gear 1 which, in tandem machines, etc. is inmesh with the pinion 8 of shaft 9 that runs to the next seat post of thetandem. Alsoin mesh with the drive gear is the pinion ll of the stubshaft ii, Journaled in the framework i2 secured by brace I; to the 5seat post and by brace l4 to the pedal-shaft bearing. The frame piece orblock I2 is connected by brace rods I! to a block it secured by bracesl'l tothe steering post jacket I.

Fast to the stub shaft II is the large gear I! 10 in mesh with pinions20, 2| fast, respectively,

: upon transmission shafts 22, 23 also Journaled in the blocks i2, i6,said shafts 22, 23 having facilitate assembly of the handle bar In itmade in two sections, the meeting ends as threaded and screwedtogetheras shown at lb in Fig. 2. The handle bar is secured to thesteering post by the head 29 having threaded therein the vertical rack3| for engagement by the pin 32 that extends through the casing 38 sosecured by the clamp 34 to the handle bar, a spring 35 within saidcasing serving yieldingly to retainthe pin in locking engagement withthe rackteeth.

The pin 32 isslotted to receive a screw 20 to 36' I prevent the pin fromturning in its bearings.

-A cord 38 secured to the pin passes through the guide collar 31 clampedto the handle bar and through a like collar 38 and is secured to one endof the hand lever 38 fulcrumed to a strap 40 40 made fast to the handgrip 4| of the handle bar. The spring 42 of lever 39 yieldingly retainsthe same in off position so that the handle bar is releasably locked tothe rack 3|. When the lever 39 is manually pressed toward the 45- handgrip the cord 36 withdraws the pin 32 from the rack thus permitting thehandle bar to be raised or lowered and when adjusted as desired thelever is released and the pin and rack again locked in engagement witheach other.- A cord 43 running from the handle bar to the aileron, notshown, serves to transmit movement of the former to the aileron to causean altitude adjustment of the air craft. The cord 42 is fast to the pin43a that extends through the slot 43b in 64 2; I 1am I the head a and mni-mam, ind m; vents lonzitudinai movement oi the same in the head.-'
